circuit breakers.
2. Open all discharge valves
and al low water to rise in
sump pump.
3. Turn H-O-A switch to Hand
po si tion on one pump and
notice op er a tion. If pump is
noisy and vi brates, rotation
is wrong. To change rotation
interchange any two line leads

Maintenance
As the motors are oil filled, no
lu bri ca tion or other main te nance
is required.
If a seal failure unit is used, no
and
operate
at ten tion is necessary as long
as the seal shows sat is fac to ry
operation.
If seal failure is not used, the
pump should be lifted once every
two years and the oil be drained
from the seal cham ber to check
for water.
If the pump is used on a Hydr-
O-Rail system, it should be
a
high
leg
lifted once every six months and
checked for cor ro sion and wear.
